For interior decorating preparation (keying gloss paintwork, removing loose paint, rubbing down emulsion-painted walls, etc.), what type of electric sander is best?
Should I consider orbital or random orbital? Palm size, one-third sheet or half sheet? Or a circular abrasive sheet?
I would hope to find something suitable that did not vibrate too much, and which would let the dust be sucked up a vacuum cleaner attachment. Is it an advantage to have a sander with variable speed?
